DRIVING MECHANISM FOR NUMBER-INDICATING MACHINES.

To In whom, it may concern..-

Be it known that I, Ilannv 'l. Goss, a citizen oi the United States, nmla resident of Rutherford, county of Bergen, State of New Jersey, haveinvented a new and useful Imirovement in Driving Mechanism for Num-)er-lndicuting Machines, of which the following is a s mcilieation.

M y invention relates to driving mechanism for number-indicnting maclines.

It is shown in the accompanying drawings as embodied in annddiug-nmehine where numbers corresponding to the values of keysdepressed are set. up and printed and areadded upon adding-wheels. Itis, however, not limited to use in connection with suchmachines,although peculiarly applicable thereto.

The object of my invention is to provide means for enablingnumber-indieating machines to be operated by a rocking or reciprocatinghandle or member, in which machines nevertheless the main driving-shat tor driving member will be driven in one direction 0||l also, for causingthe motion of the driving member due to the motion of the reciprocatingmember in one direction to diil'er in amount from its motion due to themotion of the reciprocating member in the other direction, andpreferably to cause the initial movement of the handle to rotatethedriving-shai't a greater distance than it will be driven on thereturn movement of the handle; also, to provide means for positivelylocking the moving parts together during their respective movements toinsure accuracy and certainty ofepcration.

, In the drawings accompanyin this SPOOlll'. cation and t'ornnng an'thereof have shown one form or ember iment of my inventions As thereembodied it is used in connection; with the driving mechanism of aprinting and adding machine in which keys representing different valuesare employed, the depression of which keys brings corres ending type 11on a line for printing or adr ing purposes. 10 use of my invention isnot, hew i swam,

The machine is operated by depressing the desiredkeys, and then the operating-handle 4 is pulled orward by theoperatorand then pushed backward or returned to its beck ward positionby any suitable means. 'lais, operation of the machine sets up typecorre-' sponding to-the keys depressed upon a print in -line and addssuch numbers to'the total editing-wheels. None of these parts except themain driving mechanism of the machine. wluclrwdl be presently described,form. part of my invention, and such parts not shown and will not bedescribed. "1 mav be of any suitable construction.

1 eferring new to the form of-my impro drivin mechanism shown in thedrawing revir e a driving member adapted .on only a d -shaft BESTAVAllJiEJLl continuous rotation of the other. These connections are soarranged and shaped that the movement of the handle 4 in one directionwill cause the main driving-shaft 5 to 5 be rotated a different distancefrom that imparted to it by the movement of the handle intheoppositedirection. I prefer to-"arrange the parts so that the forwardor initial movement'of the handle 4 will cause shaft 5 to rotate agreater distance than it will be rotated by the return of handle 4 toits original position. .In ,the form shown in the drawings theforwardmovement ofhandle 4 rotates shaft 5 two-thirds of a-completerevolution, while thebackward or return movement of the handle willrotate the shaft the remaining one-third. The connections shown for thepurpose are as follows: 7 is a plate fast to s raft (i. 8 is a platelooselymounted on the shaft. Slidingly mounted on plate 8 is aslide-plate 9, 11min an extension 10, movable between stu s 11 of plate8. Sliding plate Dis capable of a sliding movement on plate 8. -'lhissliding plate is provided with two reversely-acting setsof gearingl'iland 13. These sets of-gearing are arranged at different radial distancesfrom the center of rock-shaft-G and when operative concentric therewith.one gearing, 3 12, facing outward from the center, the other,'13,"faeing inward. 'ihese ears 12 and 13 are so arranged that if sliring platei) is in its outward radial position gearing 12 will mesh withgear-wheel 14 and gearin 13 will 5 beontofmesh whileif the slidingpateis in its inward radial position gearing lli will mesh with the oppositeside of gear-wheel 14 'and gearin 1'2 will be out-of mesh. Means areprovided for throwing one of these 1 40 sets of gears into mesh withgear-wheel 14 when rock-shaft 6 rotates one way andthe other into'meshwithit when the shaftmtatestheother way. i In sliding ilatei), is a cam'slot 15 in which works a re ler..10,"attached to plate The upper partofplate 7 has atooth 1 7.' Mounted-on plate 8, is a pawl 18, which hasanextension .19 at the right and anex'tension atthe left., Thecam-surfaceson? these extensions are adapt-1 ed in the different positions of, theartsrtp: pins' 21, mounted on the side rame of ichine. .Mountcd onplates are ,twol

and 22, and coactin with these pins,- canted on the side: rimmeoflthema-t are' two 1pawls '23,*'wh icl' H ed and. rave limiting. opsk2424ginus a teeth 25 coactpig-withtooth' with gear-wheel 14, while gearing 13is out of mesh. The forward movement of handle 4 will eauseplate 7tobegin to move to the left as viewed in Fig. 2 and will carry roller 16to the left-hand end of slot 15. The shape and slope of this cam-slot issuch that this first movement of the parts will move sliding plate 10inwardly, taking gearing 12 out of mesh with gear-wheel. 14 and throwinggearing 13. into mesh with it on its opposite side. A slight furthermovement of the handle will free extension 19 from pin 21 and spring26-will pull pawl 20 downward, bringing tooth 25 in line with tooth17.-Plate 7 and its teeth 17 will, however, by this time have moved farenough to the left so .that tooth25 will drop bael; of tooth 17. At thismoment roller 16 will have reached the-forward or left-hand end of slot15. In this 0- sition of the warts, with roller-16 at-the cft of slot 15and tooth-17, plates 7 and 8 will be rigidly locked together,.so thatthe forward movement of plate ,7 will carry with it plate 8 and all ofits parts the same-as if they formed parts of one rigid structure. theimportant features of my improvement, and it isessential foratheaccurate and reliable working ofa ra iid adding or printing machine. 1Further orward movement of teeth 25 immediately back of.

-'ihis rigidity is one ofthe handle will cause gear wheeI 1-4 to rotatehen handle 4 'begins gear,1'4,and freeing pin 22 from awl23,'perv,mitting=the return its connections.. I v y Fig. 1 illustrates thepositiomofthe parts movement 0 plate 8; and

whenmidw'a ;ontheir forward movement Y and iii 51w ien the have reachedthe extreme rwardipositron. When the return pawl 25 becomes disengagedfrom pm -21 am to' oth-25 f :drops backward. 1 .By this -.tir ne .qgtlhas movedseilieientlv to the reiar'to 1: rent movement has; proceeded a.short distance The purpose of this spring is to return the parts totheir original or normal positions in case the operator lets go of thehandle while on its return or does not push it far enough back. Spring27 is so proportioned that it will bring the parts back to theiroriginal positions in such case. As the parts reach their originalpositions pawl 23 again looks with pin 22, locking plate 8 and itsconnections in their original positions, and extension 19 of pawl .20strikes against pin 21, leaving tooth 25 out of engagement with tooth17, preparing the parts for the next operation of the machine. Therevcrscly-aeting gears, facin in opposite directions and operating upondif ferent sidesef the gear-wheel 14 when successively in engagementwith it, r'etate that gear, and with it the main driving-shaft, alwaysin the same direction. The arrangement of these gearings l2 and 13 atdifferent distances from the center of the rock-shaft enables the maindriving-shaft to be rotated a greater distance when handle 4 is moved inone direction than when it is moved in the other. As shown, these partsare so proportioned and arranged that on the forward or initial movementof handle 4 shaft 5 is retated two-thirds of a complete revolution andon the return of the handle it is rotated the remaining one-third of a.revolution. One

advantage of this arrangement is that practic-ally the entire workperformed by the machine is accomplished on the forward ml] of handle 4.Substantially no work need )eperformed on the return of the handle, exec1b to return to their original positions a few 0 the parts of themachine and that, too, when running free. By means of my improvedarrangement the return-sprin v '27 can be made comparatively very light.Vhere this spring is made stron as it must be where a COI1Sl( erable)art 0 the work is done on the return of the iandle, the amount of workto be don e by the operator in operating the machine 18 verylargelyincreased. Inpractice it has been found that the ordinary operator willnot imparted to the main driving-shaft of the machme,while theoperating-handle may have a reciprocating movement. This is of greatadvantage as it has been found in practice that machines of thecharacter shown in the drawings are more easil operated by means of areei rocating, ham ethanbymeans of one ma ing a completes,revolution.By-v means'of my nnprovement; such machines can bemade very rapid,accurate, and positive in operation. In order that gear 12 may BESTAVAlLABLE machine is very rapid in its operation.

pass in front of gear 28 on shaft 5,"'ear 14 is made of double width, sothat geau 12 and 13 may mesh with the front half of it, while gear 28meshes with the rear half.

Figs. to 13, inclusive, show a modification of the means for locking thelates 7 and 8 together. Instead of the aw and its teeth and extensionsMN ins 21 I provide two spring-actuated paw s 29, pivoted to plate 8,and two pins on the framework, against whichthey strike on the extremelimit of movement. of the parts. Normally pin 30 holds right-hand pawl29 out of engagement with teeth 17. ()n the further movement of theparts to the left roller 16 moves to the left-hand slot 15 and ridesunder and past the point of the left-hand pawl 29. It is there heldbetween the extreme lefthand end of slot 15 and pawl 29, and thus locksplates 7 and S rigidly together. 17 is isengagcd from its pawl when thelat ter strikes pin 30 at the extreme limit of the forward movement ofthe parts, whereupon pin 16 moves to the other end of slot and engageswith the other pawl 29, thus locking plates 7 and 8 rigidly together forthe return movement. In these figures I have shown a further means forpreventing sliding plate 0 from moving rapidly inward or outward duringthe forwarr or backward movement of the parts. As there shown, slidingplate 9 is provided with a tooth 31,and 32 is a fixed flange or rail ona plate 33, secured tothe framework. This flange or rail is concentricwith shaft (1. movement of the parts when plate 9 is in its inwardmsition teeth 31 runs on theinner side of lange 32; but on the returnmovement of the parts, when sliding plate 9 is in its outward positionteeth 31 runs on theoutward or upper side of flan e 32, thus offectuallpreventim' any radial movement of the s idmg plate r uring eithermovement. By my improved devices a number-indicating machine may beoperated by means of a reciprocating handle and yet the advantages ofcontinuous rotation ofthemam driving shaft or member be retained. Themachine is more easil operated than where a rotating crank-hand e'isemployed. There is less .wear and tearon the machine than where thedriving and operating parts reciprocate movement, and-it'is more rapidin o eration and more accurate andreliable t tan such machines. Theseadvantages are attained without sacrificing the rigidity essential insuch parts to rapid, accurate, and cortain"operation. "These areverygreat advanta es in machines of the character of the ones owninpart'inthe drawings, which Tooth -By'my'im rovementthe reaterpart ofthe-work oft to machine can o done by one, movement of the reei roeatinghandle, preferably the initial or orwardone. This enables a;-- pring ofless power to be employed for the-return of the handle, and as aconsequenc i considerable less power is required to operate the machine.

My improvenent has heendevised in connection with the oonstrtnztion ofthe addingmachine shown in part in the drawings, the rest of whichmachine is not an invention of mine. My invention, however, is notlimited to in its use in connection with such nuiehines.

Many modifications and changes in the form of devices shown in thedrawings may be made without departing from my invention.
